Can repeat said process, up to the turn layers (for brevity, only figure 3 illustrates three turn layers) that in elementary winding 10a, forms requirement.
Should be noted that and to use continuous insulating material belt (not shown) to replace insulating paper 18.Particularly, can before electric conductor 16, twine this continuous insulating material belt continuously, to provide and insulating paper 18 essentially identical insulation characterisitics.This insulating tape can use the known routine techniques of technical staff in the design of transformer and the field of manufacturing at the end of this layer it to be cut out to suitable length around the certain layer of electric conductor 16 then.
In addition, can on plug, twine elementary winding 10a, and subsequently it is mounted on the first winding leg 104, replace directly on the first winding leg 104, twining elementary winding 10a.
Can on the first winding leg 104, twine secondary winding 11a according to above-mentioned method then for elementary winding 10a explanation.The number of wire turns of each layer electric conductor 16 and inequality among primary and secondary winding 10a, the 11a.Primary and secondary winding 10a, 11a are basic identical aspect other.

oCan calculate the initial resistivity value R of this electric conductor divided by its initial current by the initial voltage on the electric conductor 16
o
After adhesive 18b fusing, in about 130 ℃ ± about 15 ℃ target zone, keep predetermined amount of time to cause this adhesive 18b curing the temperature of elementary winding 10a.(this predetermined amount of time can be, and for example 20 to 90 minutes, this depended on the size of elementary winding 10a.) when arriving the terminal point of scheduled time slot, but interrupt flow is crossed the electric current of electric conductor 16, and this electric conductor 16 and DC power supply 120 and variable power regulator 121 are disconnected.
Can need not so elementary winding 10a is placed in the hot-air convection heating furnace is fusible and cure adhesive 18b.Therefore, by using this method for optimizing, can eliminate with elementary winding 10a to or shift the time be associated from the hot-air convection heating furnace.
In addition, believe when using this method for optimizing to replace hot-air convection heating furnace that fusing cycle required with solidifying this adhesive 18b is in fact lower.Particularly, use electric conductor 16, believe and can heat elementary winding 10a quickly as thermal source, and more even than the mode of hot-air convection heating furnace.Thereby the comparable use hot-air convection of the temperature of elementary winding 10a heating furnace is stabilized in desirable value quickly.Therefore, use this method for optimizing can realize the minimizing of the cycle time relevant potentially with making elementary winding 10a.
In addition, use electric conductor 16 can realize more uniform heating, believe that this also can produce more homogeneous mechanical joint at insulating paper 18 and 16 adjacent of each electric conductors as thermal source.The joint that improves is for elementary winding 10 particular importances of innermost layer, and use hot-air convection heating furnace is difficult to heat winding herein.
In addition, believe that in fact the institute's energy requirement that uses the elementary winding 10a of current flow heats that flows through electric conductor 16 will be less than the institute's energy requirement that uses the hot-air convection heating furnace to heat elementary winding.Therefore, by using this method for optimizing to obtain potentially because the cost savings of using energy still less to bring.
Next can melt and solidify the adhesive 18b among elementary winding 10b, 10c and secondary winding 11a, 11b, the 11c according to method for elementary winding 10a explanation.Replacedly, elementary winding 10a, 10b, 10c and secondary winding 11a, 11b, 11c can be electrically coupled to DC power supply 120 and variable power regulator 121, and can melt and solidify the adhesive 18b among each elementary winding 10a, 10b, 10c and secondary winding 11a, 11b, the 11c basically simultaneously.
